B&K 2245 with Product Noise Partner App

Fast, Standards-based Product Noise Testing – From Setup to Report

Product Noise Partner is a focused workflow-based app for measuring and documenting product noise with B&K 2245 sound level meter – helping you determine sound power levels to ISO standards, benchmark designs, and generate clear compliance-ready outputs with minimal effort.

Key benefits

• Reduce mistakes on site with guided setup and a 3D geometry view that helps ensure all measurement positions are covered.
• Get results immediately with instant final outcomes and pass/fail indications when measurements are complete.
• Work efficiently from field to office using coordinated mobile and PC apps for capture, calculation, and reporting.
• Strengthen traceability by embedding metadata and media alongside each measurement for audit-ready documentation.

Key features

• Measurement of sound power using measurement methods that fulfil the ISO 3744 and ISO 3746 standards
• Measurement of sound pressure levels of toys (from close-to-the-ear toys, table-top or floor toys, and handheld toys) according to EN 71-1
• Simplified user interface with 3D geometry view to guide measurement positions and reduce missed points.
• Instant results showing final test outcomes and pass/fail indications upon completion.
• Wireless control from your smartphone so you can operate away from the measurement point and avoid influencing the sound field.
• PC-based workflow from choosing a standard, defining device geometry and measurement positions, through to calculating the final result. You also have the option to control measurements remotely from the PC.
• Rich annotations: add customizable metadata, plus pictures, text and voice notes, and videos.

Typical applications

• Measuring and reporting of sound power levels to demonstrate product compliance with noise specifications for legislation or commendation
• Assessing noise emissions from toys according to EN 71-1
• Determining noise emissions of machinery and equipment for ensuring compliance with standards or benchmarking for comparisons
• Determining sound pressure levels at workstations
• R&D and quality assurance testing products for analysis to identify and evaluate prominent discrete tones and impulsive noise

Guided measurements with minimal training

Product Noise Partner supports standards-based sound power determination by guiding you through the complete setup: select the relevant standard (for example, ISO 3744 or ISO 3746), define the product geometry and required measurement positions, then capture the measurements with the SLM under a controlled workflow.

The solution calculates the final sound power result and provides clear reporting outputs, while embedded metadata and captured media help ensure traceable documentation. The workflow can also support related tasks such as determining sound pressure levels at workstations when required.

Get the job done: In the field and back in the office

Download the Product Noise Partner app from the App Store^® to your smartphone to wirelessly take control of the SLM. Place the sound level meter at the measurement position and connect to the mobile app via Wi‑Fi^® to run the test remotely, helping you to avoid disturbing the sound field.

In the office, the PC app accelerates analysis and reporting while giving you deeper insight into the data. Perform detailed review—including ‘what if’ adjustments—and generate reports aligned with relevant standards.

Task-focused Apps For Your SLM

The base application for B&K 2245 is Noise Partner, a general noise measurement app. Product Noise Partner would be installed on top of the base, providing you with a powerful multi-application SLM solution.

You can further extend your SLM capabilities with dedicated workflows for other measurement tasks:

• Enviro Noise Partner – perform community noise surveys and compliance-oriented spot checks to evaluate the impact of a noise source and how different sources contribute to the ambient noise at the measurement position.
• Work Noise Partner – evaluate workplace noise to ensure compliance with regulations and safeguard employee safety, including determining the need and level for hearing protection. The interface guides you through a full survey and requires minimal training to ensure valid and actionable data.
• Exhaust Noise Partner – carry out vehicle exhaust noise testing such as road vehicle exhaust noise inspections and verify measurements in the field.

Each software licence is installed on the SLM. The SLM license automatically enables connection to the smartphone and desktop app versions, which are free to download!

• The iOS mobile app is available for download via the App Store
• The desktop PC app is available on our Downloads page
• Noise Partner for Android is available via Google Play™
